You are confussed because fulltime is a generatic term and some have a
posi unit in center case to be able to SEND MORE TORQUE to one axle than
the other one. (ie a Borg Warner Quadratrac used in Jeep from about 74
till 79

That is not what you wrote, I guess, because you have cut the previous
post.
If you have 3 open diffs all the power will go to the wheel with the
least resistance. Right!
This is thru for all 4wd/awd LR's. As far as I know all rangies and
disco's do have this set-up.

No the Stage One is a later model. Somewhere in between the series 3 and
the Defender.
It has the series chassis but the defender front end to fit the V8
engine. The permanent 4 wheel drive was needed to split the power
equally over all the wheels otherwise the two rear drive shafts could
snap.

Series are all part-time 4wd as far as I know.

Rovers (at least Defenders and I presume Discos too) deliver power to all 4
wheels equally (your definition of AWD) unless the transfer case is locked -
then power is delivered equally to each axle (your definition of 4WD). FWIW

Yeah, sure. off-course.
Hard to get things right in an english NG.

You really are lost here and must be using some magical open
differentail (that does not exist)that does not divide torque
equally. You just do not understand the difference between axle torquer
and HP. While torque must be the same HP (ie differnet RPM in shaft) can
be different.

I think I did and made it clear....
Didn't I? Could be a language problem though....
Kind regards again,

I have older Ford Explorers and the transfer case is about the only thing
that doesn't break often (besides the engine). On the Exploders the main
things that fail on the 4WD are the auto-hubs and the servo motor that
engages the transfer case. Both are relatively easy and inexpensive to
repair/replace. If you mark your front driveshaft with some chalk, put it
in 4WD and drive it a couple of feet you can see if the front driveshaft is
turning. If it is then the problem is most likely in the front end or the
locking hubs.

Have you checked the fluid level in your transfer case and differentials?
